BATHTUB—Design Considerations: Bathtub/shower controls installed on an end wall are part of what makes a bathtub accessible. The list includes a clear floor space, a removable bathing seat, grab bars, and a shower spray unit. Additional considerations are a turning space and the location of a nearby fixture. Other views of a bathtub and fixtures are at Lavatory and Bathtub, page 136 and Cabinet, Countertop, and Bathtub, page 152.

BATHTUB—Bathing Fixture Width: A 32 inch (813 mm) bathtub with a typical three-ply shower surround has a width of 30-1/2 inches (775 mm) between the finished back wall and the open side of this bathtub. The width is approximate and should be accurate to within 1/4 inch (6.35 mm) given standard board and tiles.

BATHTUB—A bathtub’s rough-in consideration should detail: Bathtub width, height, depth, and drain location. Net thickness of each structural wall and wall covering. Grab bar and spray bar backing locations. Control valve location. Finished floor height. Clear floor space. Turning space to and away from a bathtub.

BATHTUB—Bathing Fixture Depth: A 60 inch (1524 mm) bathtub with a typical three-ply shower surround has a depth of 57 inches (1448 mm) between the finished surface of the end wall and the finished surface of the control wall. The depth is approximate and should be accurate to within 1/4 inch (6.35 mm) given standard board and tiles.

BATHTUB WITH PERMANENT SEAT—Design Considerations: A bathtub with permanent seat's clear floor space is the depth of the bathtub and seat and 12 inches (305 mm) beyond the seat wall. This length is an important planning consideration. The clear floor space width and the location of a nearby fixture are also important considerations. Other views of a bathtub with permanent seat and fixtures are at Lavatory and Bathing Fixture with Seat, page 138. Cabinet, Countertop, and Bathing Fixture with Seat.

Building material on wall X, typically 1/2 inch (12.7 mm). 2. At minimum, 12 inches (305 mm) beyond the seat wall. 3. Length of the permanent seat and bathtub.
